Phase transitions and amorphization of M2AgF4 (M = Na, K, Rb) compounds at high pressure
Jakub Gawraczynski, Łukasz Wolanski, Adam Grzelak +3
We report the results of Raman spectroscopy high-pressure studies of alkali metal fluoroargentates (M2AgF4, where M=Na, K, Rb) associated with theoretical and x-ray diffraction stu…
Crystal structure, lattice dynamics and superexchange in MAgF3 1D antiferromagnets (M = K, Rb, Cs) and Rb3Ag2F7 Ruddlesden-Popper phase
Kacper Koteras, Jakub Gawraczynski, Gasper Tavcar +2
With the use of lattice dynamics calculation within hybrid HSE06 framework we were able to understand vibrational spectra of MAgF3 M = K, Rb, Cs compounds. Comparative theoretical…
Observation of a new polyhalide phase in Ag-Cl system at high pressure
Adam Grzelak, Jakub Gawraczynnski, Mariana Derzsi +3
In this short contribution, we examine Raman spectroscopic data from high-pressure and high-temperature experiments with Ag-Cl system, and find that they are in good agreement…
Charge Transfer and excitations in AgF
Nimrod Bachar, Kacper Koteras, Jakub Gawraczynski +11
Charge transfer (CT) insulators are the parent phase of a large group of today's unconventional high-temperature superconductors. Here we study experimentally and theoretically the…
Lattice dynamics of KAgF3 perovskite, unique 1D antiferromagnet
Kacper Koteras, Jakub Gawraczynski, Mariana Derzsi +2
Theoretical DFT calculations using GGA+U and HSE06 frameworks enabled vibrational mode assignment and partial (atomic) phonon DOS determination in KAgF3 perovskite, a low-dimension…
The silver route to cuprate analogs
Jakub Gawraczyński, Dominik Kurzydłowski, Wojciech Gadomski +13
The parent compound of high-Tc superconducting cuprates is a unique Mott state consisting of layers of spin-1/2 ions arranged on a square lattice and with a record high antiferroma…
